2nd Night: I've been looking for you.

Ko's alarm bells go off when he meets Mahiru's new friend. Mahiru may not know what Kiku is, but Ko does.

3rd Night: There aren't any ghosts in a haunted house.

A tense confrontation with Anko reveals an alarming secret: vampires have a weakness they didn't know about. Now, they all must decide their next move.

4th Night: Do you want to be able to run?

Some patients say Room 307 is haunted, and Kabura warns Ko and Nazuna to stay away. Something's in that forbidden room. Something that might hold the key to the past.

5th Night: The few years I spent with you...

Kabura thought she'd be with Haru forever. But life never goes according to plan, even for vampires. Now Kabura is left with a burden she never asked for.

6th Night: I'm not asking about the quality.

With Anko closing in, the vampires must destroy the source of their weakness before she can find them. Midori's search leads Ko and Nazuna to someone... unexpected.

7th Night: You're too stupid for that.

When Ko finds the diary of a girl called Kyoko, he discovers that he wasn't Nazuna's first human friend. Nor the first person she ever considered turning...

8th Night: You're the first, Senpai.

What began as Kyoko and Nazuna's investigation into a supposed affair led to a life-changing event that altered their relationship forever.

9th Night: Yamori-kun, what do you want to do?

Vampires cannot be harmed by conventional means, so what does Anko hope to accomplish by shooting them out in the open? Ko suspects there’s a method to her madness.

10th Night: I wanted it to be you.

As the battle between vampire and hunter erupts, Ko finally realizes the full scope of what's at stake. Now he must stop both Anko and Nazuna before it's too late.

11th Night: Mwah...

Something's wrong. Or maybe too right. Ko isn't a vampire, so why does it feel like his body's ignoring the rules? He and Nazuna need answers.

12th Night: Call of the Night

Growing up doesn't guarantee answers to life. As Ko wonders what it means to be ordinary, he and Nazuna venture through the city. Where will the night take them this time?
